本文整理了Java中java.time.zone.ZoneOffsetTransition.getDateTimeAfter()方法的一些代码示例,展示了ZoneOffsetTransition.getDateTimeAfter()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。ZoneOffsetTransition.getDateTimeAfter()方法的具体详情如下:
包路径:java.time.zone.ZoneOffsetTransition
类名称:ZoneOffsetTransition
方法名:getDateTimeAfter

ZoneOffsetTransition.getDateTimeAfter介绍

[英]Gets the local transition date-time, as would be expressed with the 'after' offset.

This is the first date-time after the discontinuity, when the new offset applies.

The combination of the 'before' date-time and offset represents the same instant as the 'after' date-time and offset.
[中]获取本地转换日期时间,用“after”偏移量表示。
这是不连续之后的第一个日期时间,此时将应用新的偏移。
“之前”日期时间和偏移量的组合表示与“之后”日期时间和偏移量相同的时刻。
